Cybercriminals may be skilled, but they aren’t invincible.
Every successful attack is due to the absence or inadequacy of cybersecurity.
If you could tighten your security, you would keep intruders out of your connection.
What Is Defense in Depth?
This is in contrast with securing your web link with a single security mechanism.
Like most cybersecurity strategies, DiD originated from the military.
Although DiD takes a cue from the military, its utility in cybersecurity differs.
Instead of stalling an intruder, you create multiple defense layers to resist their attacks.
How Does Defense in Depth Work?
Defense in depth is also known as the castle approach in some quarters.
This stems from its similarities with the layered defenses in the medieval castle.
The enemy must conquer them before getting to the castle.
There are three components of a DiD cybersecurity strategy: technical, administrative, and physical controls.
Technical Controls
The goal of technical controls is to secure the resources in your online grid.
Technical controls manage access and prevent unauthorized users from entering your system.
These tools play a critical role in DiD.
But for them, cybercriminals can bypass entry protocols without any barrier.
They also help yousecure data at restand data in transit.
Administrative Controls
Administrative controls refer to user-facing measures you have in place to secure your digital assets.
Administrative controls help prevent insider threats.
If administrative-based threats or attacks arise, the controls in this area will stop them in their tracks.
Data classification precedes prioritization.
Create clear metrics for classification and group similar data into the same category to manage your security resources efficiently.
Implementing firewalls requires you to outline perimeters for traffic entry eligibility.
Any traffic that falls shorts of those perimeters will face a barrier.
Just when cybercriminals think they have bypassed your security barriers, they face multiple hindrances along the way.
Here are some of the benefits of a DiD security framework.
Active Isolated Security Zones
Isolated security zones refer to various independent security mechanisms in one online grid.
Instead of these techniques being connected, they function separately as individual entities.
Defense in depth offers you isolated security systems that make your web link more secure.
Intruders can change their tactics at any point to bypass the security defenses they foresee.
Defense in depth helps you create various defenses to tackle different threat vectors.
And this is possible with the use of threat monitoring and prevention tools.
Enforcing Data Privacy
Ensuring the highest level of data privacy is a necessity in the highly volatile cyberspace.
Data backup, a critical function of a DiD strategy, enhances data privacy.
Defense in depth leaves no stone unturned by requiring you to create multiple defenses to secure your data.
Cybercriminals don’t stop until they achieve their goals.
You make it too easy for them if you have just one or two defenses.
With a DiD strategy, you create multiple systems to protect your territory even if they are redundant.
